A complete asshole and waste of time. A Mack will play girls, cheat, pretend to love his gf, and be a complete douche to his exes who dont deserve his shit. Everyone knows him as the one to fuck over girls. A mack doesnt mean any of the shit he will say to earn trust and forgiveness. Macks will let you think your in love and knows how to sweet talk, but inside its all a game for him. Macks should be hated by all.
